Notwithstanding the foregoing, no building permit shall be required under those circumstances specified in § 125-4A of the Code of the Town of Ithaca for which no building permit is required.

Notwithstanding the foregoing, even if there is an existing violation of this chapter on the parcel, this subsection shall not prohibit the issuance of a permit to repair or replace an element of a structure or part or all of a system when the Director of Code Enforcement determines that such repair or replacement is necessary to maintain the structure's integrity or to protect the occupant's or public's health, safety or wellbeing.
